How to provide viewModelScope as a constructor injection through hilt to other classes which are viewmodelscoped

[nilTheDev]

Didn't understand what you want to say. You want to provide instantiation of other classes as a dependency to your viewModel? And want them to be viewModel scoped?

[Ravin Jain]

Nope i want to provide the viewModelScope as dependency to other classes which are created by hilt

[nilTheDev]

viewModelScope is just a term to describe the life-cycle of a viewModel. How can you provide a dependency of viewModelScope?

[Ruslan Iusupov]

Describe your use case. Looks like what you are trying to do is wrong at the design level.

[Ravin Jain]

I have a compose screen with a viewmodel and I have few classes which are created by hilt which needs a scope and I want the coroutines created in those classes to be cancelled when the viewmodel is gone
That's y I was trying to use the viewmodel scope

[Ruslan Iusupov]

Does the viewmodel use these classes?

[Ravin Jain]

@nilTheDev what do u mean it just a term it's a cancellable coroutine scope which is cancelled on clear of viewmodel
But u can still create objects in viewmodel which are dependent on viewmodel scope
I just want to know if we can do it using hilt

[Ruslan Iusupov]

If the viewmodel uses these classes you should expose suspend functions.

[Ravin Jain]

It's not one level of hierarchical classes it's multi level and also some callbacks internally which need the same scope
Also https://link.medium.com/N718FKWEdkb article from roman suggest to pass the scope in function

[nilTheDev]

Ohh... My bad.... I thought you are talking about the @viewModelScoped annotation that scopes the lifecycle of the dependencies to the viewModel
